DESCRIPTION
The II340GY/GR bi-color intelligent indicator is a 3 x 4
cell assembly with a built-in CMOS shift register and
LED drivers. Each cell or pixel has a green and yellow
LED (GY) or a green and red LED (GR). To turn a LED
“ON” a 1 (high) has to be clocked into the respective
shift register (see the block diagram). The serial clock
has to be provided to pin 4, the “shift register clock.”
The serial data bit stream is clocked in on the falling
edge of the clock pulses.
The blanking pin can be used to blank the indicator
while the data is being updated and it can also be
pulse width modulated to dim the display and con-
sume less power.
Cascading multiple indicators is possible because of
the data out and data in pins. Notice in the block dia-
gram that only 24 LED drivers are used while 28 shift
registers are available. So when multiple indicators are
cascaded data for the next indicator will only be at the
data out pin after the twenty eighth clock pulse.
